If you get them as little babies, you will need to get milk replacer or have a source of goat milk. Bottles are messy and stinky too. But the bonding time you have when you are bottle feeding them is priceless. I used to breed and raise Nubians. Three is a good number. You should not get a buck unless you plan on castrating it. They pee on their faces to "show off" and attract the females and they drink the pee too. And they run around with their tongue hanging out and they stink so bad. You will smell like them if you stay in the barn too long. If I never smell a buck again it will be too soon. plus you will have to deal with babies if you have two girls and a buck. And then if you keep any of the babies, you cant keep them all together or they will inbreed. It is way too complicated if you just want them for pets. If you want girls, does that are grades are cheaper than show quality does, but whethers might be a more economically friendly option. The dairy's sell their whethers and bucklings for super cheap sometimes. One around here had them for $10. A good way to find out what breed of goat is right for you is to go to a fair, if you are not planning on getting them super soon. That way you can see all the goats and even talk to the people there about what their favorite breeds are and why.
